I was awarded only 35 tier points instead of 140 I should have gotten for a business class ticket. Finnair terms and conditions stated that only Finnair Plus points would be awarded according to the original booking class. As a member of Executive club and not Finnair Plus, I should receive business class tier points."
Upgraded flights on AY do not earn more BAEC Tier Points.
